Answer:
The slope of the line that joins the points is negative.
i.e m = -6/5
Step-by-step explanation:
Taking two points from the graph to determine the slope
Finding the slope between (-3, 4),(2, -2)
'
Therefore, the slope of the line that joins the points is negative.
i.e m = -6/5
You are given a set of data regarding the truck with the <span>distance y, in miles, traveled by a truck in x hours:
Time (x) (hours) 1 2 3 4
Distance (y) (miles) 50 100 150 200
I used excel to plot this data and get an equation and the value of r to anwer the following questions.
Part A: The most likely value of the correlation coefficient of the data in the graph is 1, meaning that the distance travelled by the truck and the time it takes to travel is directly related or directly proportional.
Part B: From the graph, i got an equation y = 50x with a slope of 50.
Part C: The table presented above is a correlation because both variables are directly related and forms a straight line rising to the right.</span>
Answer:
Step-by-step explanation:
Let
x -----> the number of hours
y ----> the total cost to rent a bike in dollars
we know that
The equation of the line in slope intercept form is equal to
where
m is the slope or the unit rate of the linear equation
b is the y-intercept or the initial value
In this problem we have
The unit rate or slope is equal to
The y-intercept (value of y when the value of x is equal to zero) is equal to
----> (fee charge)
substitute the values

Step-by-step explanation:
160lb.
The mean of the weights of a group of 100 men and women is 160lb. If the number of men in the group is 60 and the mean weight of the men is 180lb, what is the mean weight of the women? For a set of data, the lower quartile is 19, the median is 31, and the upper quartile is 48.
Answer:
a. 100.48
b. 1,004.8
c. 1,105.28
Step-by-step explanation:
a. a cone with volume = ⅓×3.14×4²×6=
100.48
b. a cylinder with volume = 3.14×4²×20=
1,004.8
c. total volume = 100.48+1,004.8
= 1,105.28
